Launched in 1958, Darkover is a mix of fantasy and science fiction comprising 25-books which have been translated into 17 languages. Details of the TV series adaptation are sketchy, but it is described as an ambitious tale tracing the development of a civilization from its inadvertent founding on a distant planet by a group of human colonists through war-torn feudal ages to recontact 2,000 years later with their Earthly descendants.

Sarnoff and Macmanus will executive produce the project with Ilene Kahn Power (Traffic) and Elizabeth Stanley.

Macmanus is repped by CAA, The Cartel, and attorney Stephen Breimer. Sarnoff is repped by WME and attorney Lev Ginsburg.
